In no way is this disappearance of specialisation more marked than in military and naval affairs. In the great days of Greece and Rome war was a special calling, requiring a special type of man. In the Middle Ages war had an elaborate technique, in which the footman played the part of an unskilled labourer, and even within a period of a hundred years it took a long period of training and discipline before the common discursive man could be converted into the steady soldier. Even to-day traditions work powerfully, through extravagance of uniform, and through survivals of that mechanical discipline that was so important in the days of hand-to-hand fighting, to keep the soldier something other than a man. For all the lessons of the Boer war we are still inclined to believe that the soldier has to be something severely parallel, carrying a rifle he fires under orders, obedient to the pitch of absolute abnegation of his private intelligence. We still think that our officers have, like some very elaborate and noble sort of performing animal, to be “trained”. They learn to fight with certain specified “arms” and weapons, instead of developing intelligence enough to use anything that comes to hand. But, indeed, when a really great European war does come and lets loose motor-cars, bicycles, wireless telegraphy, aeroplanes, new projectiles of every size and shape, and a multitude of ingenious persons upon the preposterously vast hosts of conscription, the military caste will be missing within three months of the beginning, and the inventive, versatile, intelligent man will have come to his own. And what is true of a military caste is equally true of a special governing class such as our public schools maintain. The misunderstanding that has given rise to this proposition that this is an age of specialisation, and through that no end of mischief in misdirected technical education and the like, is essentially a confusion between specialisation and the division of labour. No doubt this is an age when everything makes for wider and wider co-operations. Work that was once done by one highly specialised man—the making of a watch, for example—is now turned out wholesale by elaborate machinery, or effected in great quantities by the contributed efforts of a number of people. Each of these people may bring a highly developed intelligence to bear for a time upon the special problem in hand, but that is quite a different thing from specialising to do that thing.
